Robotic Bees Are Now Being Built To Pollinate Crops Instead of Real Bees

Published on October 7, 2016 by   ·   No Comments
Honeybees pollinate almost a third of the food we consume, but they’ve been dying at alarming rates due to threats like habitat loss and disease, as well as colony collapse disorder (CCD), the phenomenon where worker bees abandon their hives, leaving behind only the queen bee and enough food and nurse bees to help take care of the immature bees and the queen. There is also increasing evidence of a direct link between neonicotinoids, which are the most common type of insecticides, and CCD.

Then, last week, federal authorities placed seven yellow-faced bee species native to Hawaii on the Endangered Species Act.

And while honeybees have been dying off in many countries over the last decade, causing widespread concern over how much of the world’s food crops will get the pollination they require, different authoritative approaches have been implemented. The White House gave a task force a mere 180 days to create a plan to protect bees and other pollinators, for instance. The National Pollinator Health Strategy plans to:

  • “Restore honey bee colony health to sustainable levels by 2025.”
  • “Increase Eastern monarch butterfly populations to 225 million butterflies by year 2020.”
  • “Restore or enhance seven million acres of land for pollinators over the next five years.”

But other scientists have taken different avenues for dealing with the crisis, using modern technology to replace living bees with robotic ones. Researchers at Harvard Universityintroduced the first RoboBees back in 2013. Led by engineering professor Robert Wood, the team created bee-size robots that can lift off the ground and hover midair when connected to a power supply.

The details were reported in the journal Science. Harvard graduate student and mechanical engineer Kevin Ma, who co-authored the report, noted that the team is “on the eve of the next big development” and that the robot “can now carry more weight.”

Prior to this development, it had been impossible to put all the necessary things to make a robot fly into such a minuscule structure while still keeping it lightweight enough to actually stay off the ground, but the Harvard researchers believe that these RoboBees could, within a decade, artificially pollinate a field of crops.

The White House determined that the loss of bees and other species “requires immediate attention to ensure the sustainability of our food production systems, avoid additional economic impact on the agricultural sector, and protect the health of the environment.”

The RoboBees aren’t exactly a solution just yet, however, as they still need to be able to fly on their own and communicate with each other to perform tasks like a real honeybee hive is capable of doing.

“RoboBees will work best when employed as swarms of thousands of individuals, coordinating their actions without relying on a single leader,” explained Wood and colleagues in an article forScientific American. “The hive must be resilient enough so that the group can complete its objectives even if many bees fail.”

And while Wood explained that CCD and its threat were part of the reason for producing the robotic bee, he says the devices aren’t actually supposed to replace natural pollinators indefinitely. This means, despite their efforts, the focus should still remain on how to save these essential creatures.

The RoboBees would serve as “stopgap measure while a solution to CCD is implemented,” the project’s website cautions.

WHY NOT JUST GET RID OF PESTICIDES? 

s it a little to late? It seems that we’ve known for years that pesticides are killing millions of bees, if not billions. More specifically, it’s neonicotinoid pesticides that have been targeted as the culprit, and the province of Ontario, Canada is doing something about it. Ontario’s government recently made the decision that neonicotinoid pesticide use will be reduced by 80 percent no later than 2017.

Neonicotinoid insecticides persist in very high levels in planter exhaust material produced during the planting of crops treated with these insecticides. This runs contrary to industry claims that the chemicals biodegrade and are not a threat, they lied. These pesticide components are found in soil, they are also found in fields where the chemicals are not even sprayed. Bees also actively transfer contaminated pollen from primarily pesticide treated corn crops and bring it back to their hives. Furthermore, bees transfer these pesticides to other plants and crops that are not treated with the chemicals, which goes to show just how persistent these chemicals truly are in the environment.
